Chess.com unfairly banned my old account

bro some people do and its just to poke fun and something you shouldn't really take seriously there's no need to assume if someone does that they have some sort of a "mental problem"
Dude was elo shaming. That ain’t poking fun
either way it isn't the reason why he got banned. make your own forum if you want, not here
I never said it was the reason. I said that the fact that he did that discredits his claims that he wasn't sandbagging his games on purpose slightly.

Generally to lower their rating. Sometimes they do this to get into rating-restricted tournaments they can easily win. Sometimes they do it to troll other players ("Haha, you lost to a 100-rated player!"). Sometimes they do it to get easier games they can win more easily. There are other reasons, but those are probably the main ones.
I see a lot of games resigned in the opening in late January and early February. That looks like sandbagging to me.
Rare to see a Gleason thread comment
I usually live in the Cheating Forum.
